Alright, i want this thread to be a serious one because i honestly want to know what christians believe.

I want to know a couple of questions.

If someone kills millions of people but repents completely and accepts jesus as his savior will he be accepted into heaven?

Do people of all religions other than christianity burn in hell for all eternity?

Is Ghandi in heaven?

If someone miraculously lives without sin his whole life and is the nicest person in the world but doesnt accept jesus as their savior will they burn in hell forever according to the christian bible?
